Evaluation of Synchrony in the Post-operative Patient (SYNCHRONY)

This study has been completed.

Last verified: January 2015

Neurally adjusted ventilatory support improved synchronization in the medical patient. However no data are available in the postoperative patient.

This way the investigators designed a prospective randomized cross over trial to evaluate this issue in the abdominal post-operative patient.

Condition Intervention
Patient-ventilator Asynchronism
Device: MAQUET SERVOi ventilator with Edi Catheter
Device: MAQUET SERVOi ventilator

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Open Label
Primary Purpose: Basic Science
Official Title: Evaluation of Synchrony in the Post-operative Patient (NAVA vs Pressure Support)

Further study details as provided by Hospices Civils de Lyon:
